Maintenance - ProFlow PF-SOF1,5-SIM Installations- Und Gebrauchsanleitung

ROUTINE CHECKS
Regularly the user should perform a basic check to verify if the
appliance is functioning correctly, on the basis of the
following control points:
1. Check settings of electronic control panel.
2. Measure water hardness before/after appliance.
3. Check drain line from control valve; there shouldn't be
any water flow (unless appliance is in regeneration).
4. Check drain line from brine tank overflow; there shouldn't
be any water flow.
5. Check appliance and surrounding area; there shouldn't be
any water leakages.
BYPASSING THE APPLIANCE
Occasionally it may be necessary to put the appliance
hydraulically in bypass, i.e. to isolate it from the water
distribution system; f.e.:
in case of an urgent technical problem;

when it is not necessary to supply treated water to the

application.

WATER CONDITIONER SALT
This appliance needs 'brine' for its periodic regenerations.
This brine solution is made from water, that is automatically
dosed in the brine tank by the control valve, and water
conditioner salt. The user should make sure that the brine
tank is always kept full of water conditioner salt. Therefore he
should periodically check the salt level inside the brine tank
and refill it if necessary. Simply lift the brine tank cover to
check the salt level inside the brine tank.
Ideally the level of water conditioner salt inside the brine tank
is kept between 1/3 and 2/3. A lower level of water
conditioner salt can cause insufficient brine saturation,
resulting in a loss of softening capacity. A higher level of water
conditioner salt can cause salt bridging (hard crust or salt
bridges in the brine tank). When you suspect salt bridging:
carefully pound on the outside of the brine tank to break

loose the salt bridges;
 using a broom (or like blunt tool) carefully push the salt to
break it apart;
 pour warm water over the top of the salt to dissolve it.

MAINTENANCE

Other contaminants (f.e. iron) present in the feed water can
cause the resin bed to foul up, resulting in a loss of softening
capacity. An approved resin cleaner can be used periodically
to thoroughly clean the resin bed.
This appliance is manufactured from premium quality
material and assembled in safe conditions to assure it is clean
and sanitary. If installed and serviced correctly, this appliance
will not infect or contaminate your water supply. However, as
in any 'device' plumbed-in in your water distribution system,
a proliferation of bacteria is possible, especially in case of
'stagnant water'. Therefore this appliance is equipped with a
'days override' feature, that will automatically rinse the resin
bed periodically, even in case of low or absence of water
usage.
If the power supply to the appliance is disconnected for a
longer period of time, we recommend, when the power
supply is re-established, to manually initiate a complete
regeneration.
NORMALLY CLOSED SERVICE VALVES
(only for PF-SOF1-ALT & PF-SOF1,5-ALT)
 Picture 16
 = automatically operated = normally closed
 = manually operated = constantly open
The Normally Closed Service Valve in the outlet of each
Simplex system will only be opened when it is powered. To
manually open the Normally Closed Service Valve (f.e. in case
of a power failure), simply turn the white solenoid coil
counter clockwise.
